In response to the COVID-19 emergency, effective immediately, Toronto Master Gardeners has suspended all speaking engagements, advice clinics, workshops, and any other in-person events up to and including April 30, 2020.

However, our volunteers continue to work off-site to answer your horticultural questions via Ask A Master Gardener. Please submit your question via our online form or leave a message on our infoline at 416-397-1345.

For monthly tips on what you can be doing now in the garden, please visit our Gardening Tips page.

We will update this notice if there are any further developments.

Stay safe, and happy gardening.
